The filters sound amazing. There are 4 flavours of analog low pass filters with multiple sculpting options and healthy dose of non-linearity. There is some feedback internally but it is not adjustable. Oscillators are not too fancy but they sound good with independent drift. Great sound with 4x oversampling. It's a blast to play with full polyphony.

If you already have something like Diva this may not impress you much, but for a fraction of the price (usually goes on sale for about $20 ish) this is well worth it. Presets are okay but you need to start tweaking to unlock the synths full potential.
